DEF

A foliation defined by elongated domains of quartz or feldspar aggregates separated by anastomosing, mica-rich laminae.

CONT

Slaty cleavage ... develops in fine-grained rocks as a result of intense deformation, producing a partial recrystallisation of platy minerals parallel to the axial planes of the folds, i.e. perpendicular to the compressive forces. In general, this recrystallisation does not destroy all traces of bedding.

OBS

Slaty cleavage is the characteristic foliation in fine-grained sedimentary and volcanic rock deformed under archizone and lower greenschist metamorphic conditions.

OBS

slaty cleavage: term used at Natural Resources Canada - Earth Sciences Sector.

CONT

Les phyllades (très durs et à schistosité marquée (clivage ardoisier)), ont été exploités comme ardoises pendant des siècles.

OBS

clivage ardoisier : caractéristique d'un faible degré de métamorphisme dans les roches métasédimentaires. La contrainte est due au poids des roches au-dessus et la roche se casse en feuilles parallèles le long du clivage ardoisier.
